NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed August 21, 1&08.

Patented Jan. 4, 1910. Serial No. 449,650.

T all whom it may concern:

Be it known that I, CYRUS V. SHAXV, a citizen of the United States,residing at West Brownsville, in the county of Fashington and State of Pennsylvania, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to a nonrefillable bottle of that type provided with a stopper adapted to be inserted in the bottle neck after the bottle is filled and which automatically anchors itself therein so that the eX- traction of the stopper and re-filling of the bottle by an unauthorized person are effectively prevented.

The invention has for one of its objects to provide a device of this character which is of comparatively simple and inexpensive construction, and so designed as to permit the contents of the bottle to readily discharge, but practically precludes re-filling.

Another object of the invention is the provision of a sheet metal cylinder self-anchored within the bottle and surrounded by a cork or other packing ring that fits in the bottle neck and which contains a valve device that automatically opens when the bottle is inverted, and closes by its own weight and that of weighting members bearing on the same.

With these objects in View and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a central vertical section of a bottle neck provided with the improvedstopper. Fig. 2 is a perspective view of the stopper removed. Fig. 3 is a horizontal section of the cylinder immediately above the cross wires, the remaining parts being removed therefrom. Fig. 4 is a view similar to Fig. 3 showing the conical shield in position.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawing, A designates the neck of a bottle or other container which is molded or otherwise formed with an internal flange 1 at its upper edge and with an annular groove 2 at about the middle of the neck that provides opposed shoulders 3 and l. The stopper device comprises a hollow metal cylinder or tubular piece 5 that has its upper end expanded and provided with longitudinal slits 6 for forming spring members 7 which will yield inwardly when the tubular piece is inserted and will spring outwardly under the flange or shoulder 1 for anchoring the said piece in position. EX- tcnding around and rigidly secured to the inner end of the tubular piece is a cork or other packing ring 8 which enters the groove 2 and engages the shoulders 3 and at to assist in holding the cylinder 5 in place, and also prevents liquid from passing out around the outside of the cylinder. Within the cylinder and adjacent the inner end thereof is a conical valve seat 9 with which engages a valve 10. Disposed over the valve are weighting elements 11 that are pivoted at 12 to the cylinder 5 and bear on the top of the valve to assist in holding the latter seated. Arranged over these elements are crossed wires 13 that support a guard or conical shield let, and cooperating with this guard is a ring 15 fixed in the cylinder 5 for preventing the introduction of an instrument to force the valve open in an attempt to re-fill the bottle.

In practice, the bottle is filled before the introduction of the stopper and when it is desired to insert the stopper, the end having the ring 8 is inserted first and a pressure is applied to the upper end of the cylinder of the stopper to force the latter inwardly until the ring 8 enters the groove 2 and the members 7 spring under the flange 1. After the stopper is thus inserted, an ordinary cork stopper is placed in the upper expanded end of the cylinder 5 and pressed inwardly until the cork stopper seats against the ring 15 so as to prevent leakage of the contents in case the bottle is inverted. In emptying the bottle, the latter is inverted to cause the weighting members 11 to swing downwardly and permit the valve 10 to open by its own weight and the pressure of the liquid in the bottle. The liquid then runs out between the valve and the seat 9, past the weighting members, and between the cone 14: and ring 15, and thence out of the mouth of the bottle.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired, as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim is 1. A bottle closure and protector comprising a hollow metal cylinder provided at one end with a series of outwardly flared spring members, a valve seat located within the opposite end portion of the cylinder, a valve adapted to close downward upon the said seat, a series of weighting members grouped about a central point and pivoted to the inner wall of the cylinder and exerting a pressure upon the valve to hold the same seated, crossed wires located above the weighting members and secured to the metal cylinder, and a guard comprising complemental members, one mounted upon the crossed wires and centrally disposed within the cylinder, and the other secured within the cylinder.

2. In combination, a bottle or like receptacle provided with a neck having an inner flange 1, and spaced shoulders 3 and 4, the latter extending into the opening of the neck a greater distance than the shoulder 3, a metal cylinder supported within the neck upon the shoulder 4 and having flared spring members at its upper end to engage under the flange l, a packing ring surrounding the lower end of the cylinder and supported upon the shoulder 4 and confined between said shoulder and the shoulder 3, a valve seat arranged within the lower portion of the metal cylinder, a valve adapted to close downward upon said seat, a series of weighting members grouped about a central point and pivoted to the inner wall of the cylinder and exerting a pressure upon the valve to hold the same seated, and a guard comprising complemental members, one mounted upon the crossed wires and centrally disposed within the cylinder, and the other secured within the cylinder.

In testimony whereof I aflix my signature in presence of two witnesses.

CYRUS V. SHAW.
